Referring now to FIGS. 1A and 1B, there is shown a perspective view of the oven with automated racks and door with the door in a closed position and a perspective view of the oven with automated racks and door with the door in an open position, respectively. The oven 10 includes a base 11, a pair of opposing sidewalls 12, a rear wall 13, and a front wall 39 that includes a door 18 for providing access to an interior volume 24 of the oven 10. While the door 18 is configured to move automatically, a handle 21 is disposed on an upper edge of the door 18 for facilitating manual opening and closing of the door 18 if desired. In the shown embodiment, the handle 21 comprises an arcuate shape and extends across the door 18. The door 18 may further include a window 19 for observing the interior volume 24 when the door 18 is in a closed position. In the shown embodiment, the oven 10 is shown as a residential oven that includes a top surface 14 having burners thereon. The shown oven 10 further includes a lower compartment 20 disposed beneath the door 18. However, the present invention can be embodied in commercial ovens as well, which may or may not include the top surface 14 or the lower compartment 20.

In the shown embodiment, the oven 10 includes a rear extension 15 that extends upwardly from the rear wall 13 and perpendicular relative to the top surface 14. The rear extension 15 includes a first display 16 configured to display operations and statuses of the oven 10, such as the current temperature, cooking time, or other information. The rear extension 15 may further include controls 23 thereon for controlling the oven 10. In one embodiment, the controls 23 are buttons. In alternate embodiments, the controls 23 are enabled by a touch sensitive screen integral to the display 16. The oven 10 may further include a second display 17 disposed on the front wall 39. The second display 17 may also include controls 22 thereon configured to control various functions of the oven 10, such as temperature, cooking time, and the like. The oven 10 also includes a display panel including a door indicator 38 that is configured to illuminate when the oven door 18 is opening or closing, and a rack indicator 39 that is configured to illuminate when the oven racks are extending or retracting. The indicators 38, 39 assist deaf or otherwise hearing impaired individuals with safely operating the oven 10.

The interior volume 24 of the oven 10 includes tracks 25 disposed on the sidewalls 12 that are configured to receive support racks and trays for supporting food within the oven 10. The oven 10 further includes a lower surface 26 disposed within the interior volume 24. A door slot 30 is disposed beneath the lower surface 26. The door 18 is configured to move between a closed position and an open position via the first or second controls 23, 22. In order to achieve this, the door 18 is rotatably connected to a motor 32 at a lower end 28 of the door 18. The door 18 and motor 32 are slidably disposed within the door slot 30. An actuator 27 is secured to a rear wall 31 of the door slot 30. The door 18 is operably connected to a push rod 29 which extends from the actuator 27. The actuator 27 is configured to move the push rod 29 in a linear motion in order to extend the door 18 from the compartment 30 or to retract the door 18 into the door slot 30. When moving from the closed position to the open position, the door 18 rotates downward via the motor 32 and is retracted into the door slot 30. When moving from the open position to the closed position, the door 18 is pushed out of the door slot 30 via the actuator 37 and then rotated upward via the motor 32 until it is parallel with the front wall 39.

Referring now to FIG. 2, there is shown a perspective view of the oven with automated racks and door with the racks in an extended position and the door in an open position. The oven 10 further includes support racks for supporting food within the interior volume 24 of the oven 10. In the shown embodiment, the support racks include a grate 33 having a plurality of openings and a tray 34 having a solid base 36. The grate 33 and the tray 34 are slidably disposed within the interior volume 24 via sliding engagement with the tracks 25. The grate 33 and the tray 34 are easily accessible when the door 18 is in an open position and retracted into the door slot. Additionally, the grate 33 is disposed above the tray 34 so that food particles that fall through the grate openings do not contact the lower surface of the interior volume 24. In the shown embodiment, the tray 34 further includes a lip 35 disposed about the perimeter thereof and extending upwardly and perpendicularly from the base 36. The lip 35 prevents food particles from sliding off the edge of the tray 34.

Referring now to FIG. 3, there is shown a cross-sectional side view of the oven with automated racks and door taken along line 3-3 of FIG. 1B. The interior volume 24 of the oven 10 further includes additional actuators 27 secured to the rear wall 13 that are configured to move the grate 33 and the tray 34 between an extended position, as shown by the position of the grate 33, and a retracted position, as shown by the tray 34. Each of the actuators 27 includes a push rod 29 that is configured to move the grate 33 or tray 34 linearly into or out of the interior volume 24 of the oven 10. The grate 33 and tray 34 each slidably engage a track 25 within the interior volume 24. In an alternate embodiment, the track 25 includes one or more freely rotatable wheels 45 that contact the grate 33 and tray 34 in order to facilitate movement thereof.

In an example operation, a user may open the door 18, which rotates between a closed position in which the door is vertically oriented and covers an opening 40 on the front wall 39 of the oven 10 and an open position in which the door 18 is rotated downward to a horizontal orientation via the door motor 32 and retracted into the door slot 30 via the actuator 27. When the door 18 is in the open position, a user may extend the grate 33 or tray 34 and place food thereon, and then retract the grate 33 or tray 34 back into the interior volume 24 for cooking. When cooking is complete, the user may then extend the grate 33 or tray 34 to easily retrieve the food from the oven 10.

In the shown embodiment, the oven 10 does not include the lower compartment. In this embodiment, the door slot 30 is defined by the lower surface 26 of the interior volume 24 and the base 11 of the oven 10. In embodiments of the oven 10 where the door 18 includes the handle 21, the door slot 30 is large enough to receive the door 18 and the handle 21 extending outwardly therefrom. When the door 18 is in the closed position and retracted into the slot 30, the upper end 37 of the door 18 does not extend past the front wall 39 of the oven 10, ensuring that the door 18 is not a tripping hazard when in the open position.

Referring now to FIG. 4, there is shown a diagram of the components of the oven with automated racks and door. The oven 10 includes a power source 51, such as a connection to a wall outlet, for powering the various components. A temperature control 52 is in operable communication with a heating mechanism 53. The heating mechanism 53 is configured to heat the interior volume of the oven 10 during cooking and can be a gas heating mechanism, an electric heating mechanism, or any other known type of heating mechanism used with ovens 10. A rack control 59 is in operable communication with the rack actuators 56, and a door control 60 is in operable communication with the door actuator 57 and the door motor 54.

The door actuator 57 and door motor 54 are further in operable communication with an alarm speaker 58. The alarm speaker 58 is configured to emit an audible alert when the door actuator 57 and door motor 54 are either opening or closing the oven door. Further, the door motor 54 and door actuator 57 are in operable communication with the display panel 55. The display panel 55 may include the door and rack indicators that illuminate when the door is opening or closing and the rack is extending or retracting. In alternate embodiments, the display panel 55 can also be in operable communication with the rack actuator 56, such that a rack indicator of the display panel 55 illuminates when the rack actuator 56 extend or retracts one of the racks. In this way, individuals who are hard of hearing will be notified when the doors or racks are moving.
